Step 1: Understand what pH is. pH is a measure of how acidic or basic a solution is.
Step 2: Know that a lower pH means a more acidic solution, while a higher pH means a more basic solution.
Step 3: Identify the substances given in the options. Look for strong acids, weak acids, strong bases, and weak bases.
Step 4: Recognize that NaOH (sodium hydroxide) is a strong base.
Step 5: Remember that strong bases like NaOH will have a high pH, usually above 12.
Step 6: Compare the pH values of the other options. Strong acids will have low pH, and weak acids/bases will have pH values closer to neutral (around 7).
Step 7: Conclude that 0.1 M NaOH will have the highest pH compared to the other options.
